Lucreate fails with - .../var directory not empty

Question

Hi,
I have Solaris 10u8 with patch cluster from February2010 and patch 121430-44 installed on a V445
/ and /var are on seperate datasets
When i attempt to run lucreate i get an error as it attempts to mount /.alt.tmp.b-vI.mnt/var due to the directory /.alt.tmp.b-vI.mnt/var/tmp already existing
lucreate appears to create a /var/tmp directory in the root dataset of the the new BE during creation and is then unable to mount the var dataset.
It returns a "directory not empty" error
Attempted this multiple times same issue.
Any suggestions would be greatly appreciated.

Answer 1

I think I figured it out...
In the / dataset there is a /var/tmp that is missing the sticky bit (mode 0755) There was an anomaly during the u7 to u8 luupgrade that caused this, I think. It was a couple weeks ago and it didn't take me too long to overcome it by 'chmod 1777 /var/tmp'. But that was with the /var dataset mounted.
Unfortunately, zfs just mounts over the bad /var/tmp in the / dataset causing lumount to barf during the lucreate process because that there's already something in /var/tmp when it tries to mount the var dataset clone.
I dropped to single-user mode, force-unmounted /var, and deleted /var/tmp (which still had the 0755 permissions). lucreate works just fine now...
Good luck,
Mike
